, able others skilled in the art to which it ape pertains to make anduse the same.

The objects of this invention are to provide a simple and efficient formof printing device for common, commercial, or private use and adapted toprint either roll or web paper or paper slips of convenient sizesuitable for letter-heads, bill-heads, menus, programs, or similarmatters which are subject to frequent change from day to day.

The invention consists in a printingcylinder and pressure and inkingrollers mounted vertically in suitable supports one over the other andin the adjustable mechanism whereby the pressure upon the type iscontrolled.

It also consists in the combination and arrangement of the various partsto fit the device to its double use and in the construction of thevarious details, as hereinafter described, shown in the accompanyingdrawings, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of thedevice, showing a roll of paper attached and a paper-cutter at theopposite end of the machine. Fig. 2 is an end elevation of the same fromthe paperroll end, showing the supports for the paperroll in section.Fig. 3 is a plan view of the table of the machine, showing the secondmanner of using the same for printing paper slips of varying size andmeans for adjusting the position of the slips so that they may beregularly fed to the printing-cylinder.

In the views, 1 is the printing-cylinder, which is provided in anysuitable manner with removable type 2 and is also provided with rubberbands 3, which encircle the ends and engage the surface of thedriving-roll 4, between which and the type-cylinderthe paper is printed.

The printing-cylinder and roll 4 are mounted upon vertical plates 5,which are secured to the sides of the box 6, in which the type and otherappliances for use with the machine are kept. The roll 4 is directlymounted upon hearings in these plates upon an axial shaft 7.

The printing-cylinder 1 is adjustably and yieldingly mounted in bearingsformed in the arms 8 and 9, one set of which, 8, are pivoted each at oneside of the supports 5, and the other set or upper arms 9 are pivoted tothe arms 8 at a point above the cylinder- ;shaft 10, and the upper armsv9 are brought 5 down upon the shaft and their outer endsseicurely lockedby means of the slotted links 111 and lock nuts or screws 12. By thismeans the bearings can be made as tight as .required, and by looseningthe links fromtheir fastenings they can be dropped down and the shaftand printing-cylinder removed ;at pleasure. The outer ends of the arms 8extend beyond the shaft-bearings and are {supported by means of thescrews 13, which Ihang by their heads 14 from the lugs or projections 15upon the supports 5. Coiled "springs 16 upon these screws will make theipressure of the type upon the roll 4 positive, f but will yield to thepressure of thicker paper or card which may be passed between thefcylinder and roll, so that in lieu of a positive adjustment for onethickness of paper, as E now is customary in printing-presses, thecylinder will automatically adjust itself to all 'thickness'of paper orcardboard which may ;be required in the large variety of uses in common,mercantile,and private work, an advantage not hitherto possessed by suchFmachinery.

i The inking-roller 17 engages the cylinder by gravity and is guided inthe vertical slots 18, intowhich the axial shaft projects. Thislinking-roller is provided with elastic rubber bands 19 upon itsextremities, which engage Fwith the bands 3 upon the printing-cylinderjand are driven thereby, so that the inkingroller will be keptconstantly revolving even jwhen not engaged by the type. The roller 20;is a feed-roller and is made of felt orsome fsubstance capable ofsaturation with the ink This makes direct contact with the inking-f@roller 17 and is preferably of a difierent di- ;ameter from theinking-roller, which insures its making contact with a diiferent portioniof the surface of the inking-roller with each revolution thereof." Thisfeed-roller is also' mounted upon a shaft 21, which is secured in linearbearings 22, which in turn slide in the slots 18, and the linearbearings form the sides of the fork 23, which is provided with a handle24, so that the roller can easily be removed for renewal of the inkthereon. When not in use, this fork can be hun upon the hooks 25, shownupon the upper edges of the side supports 5.

26 is a disk mounted upon the end of the shaft of the printing-cylinderand is provided with a notch 27 dotted. A lever 28, pivoted upon one ofthe supports 5, is provided with a dog 29 and projecting handle 28. Whenthe cylinder makes one revolution and prints off the matter containedthereon, the lever drops by gravity, and the dog 29, dotted, enteringthe notch 27 in the disk 26, stops the movement of the cylinder. Thepaper, if a slip, can then be removed, or if a continuous roll or webthe slips are cut off by" means of the transverse knife 31, underneathwhich it passes. A crank 32 serves to rotate the driving-roller andcylinder; but the machine cannot be started again until the lever 28 hasbeen raised to release the disk 26.

Thus the printed matter is correctly spaced upon the paper, and there isno waste or uncertainty of movement of the machine.

When roll paper is printed, it passes underneath the rubber bands on theprinting-cylinder and is fed by friction between these bands and thepressure-cylinder. Separate paper slips, however, may or may not engagethese bands.

In Fig. 3 is seen a form of adjustable guide by means of which slips ofpaper can be properly positioned on the table'before theprinting-cylinder when they are too narrow to engage these bands, aswhen printing postal cards across the narrow way. In this view 40 and 41are the guides, one at the end and one at the side of the card. The oneat the end so locates the card thatas soon as the first line of typeengages the card it will feed at once between the printing-cylinder andpressure-roll. A spring 42, curved to firmly hold the card until it isengaged by the first line of type, is attached to the guide at the sideof the card.

The supports 43 for the paper-roll may be detachably secured to the boxby thumb-' nuts 44 or by any suitable means, and a guide-roll 45 for theroll paper is mounted in its suitable position at 46.

Having described the invention, what I claim as new, and desire tosecure by Letters Patent, is

, 1. The combination, with a box, having a platform upon its uppersurface, of vertical side supports thereon, a pressure-roller pivtheprinting-cylinder, adapted to engage the pressure-cylinder, aninking-roller above the printing-cylinder, rubber bands upon the inking-roller adapted to engage the bands upon the printing-cylinder, thesaid inking-roller provided with an axial shaft, a vertical slot in eachside support in which said shaft is adapted to rotate and have verticalmovement, a feed-roller pivoted in linear bearings, the said bearingshaving vertical movement in said vertical slots, and a fork providedwith a handle, to the sides of which fork the said linear bearings aresecured, substantially as and for the purpose described.

2. The combination with a box, having a platform for the reception ofpaper, of vertical supports thereon, a pressure-roller provided with anaxial shaft pivoted in said supports, a printing-c linder provided withan axial shaft, the sai shaft having-spring-con trolled verticalmovement in said supports,

rubber bands upon said printing-cylinder, an inking-roller above saidprinting-cylinder provided with corresponding rubber'bands, a feedroller above the inking roller making direct contact therewith, axialshafts for the inking and feed rollers, and vertical slots in thevertical supports in which said axial shafts have free verticalmovement, substantially as described.

3. The combination, with a table, and vertical side supports, of apressure-roller pivoted in said supports, a printing-cylinder,inking-roller and feed-roller mounted upon said supports and havingvertical movement therein, said cylinder and rollers being removabletherefrom, and frictionally driven by means of said pressure-roller, andguides for paper slips upon said table and a pressuresprmg in one ofsaid guides, substantially as described.

4. The combination, with a printing-cylinder and axial shaft therefor,of rigid side supports upon which said cylinder is mounted andvertically adjustable, and verticallymovable bearings therefor,comprising each an arm pivoted upon one of said supports on one side ofsaid shaft, and extending beyond the other side of the shaft, on whichsaid shaft rests, a vertical spring-controlled adjustment for the outerend of said arm, and a arm, engaging the upper side of saidshaft, and alocking device for the face end of said second-named arm, substantiallyas described.

In testimony whereof I hereunto set my hand this 8th day of February,1905.
